be going to 的用法
be going to + 動詞原形——表示將來的打算、計劃或安排。常與表示將來的tomorrow, next year等時間狀語或when 引導(dǎo)的時間狀語從句連用。各種句式變換都借助be 動詞完成，be隨主語有am, is, are 的變換，going to 后接動詞原形。
肯定句： 主語 + be going to + 動詞原形 + 其他。 eg: He is going to take the bus there.
否定句： 主語 + be not going to + 動詞原形 + 其他 eg:I’m not going to see my friends this weekend.
be going to 與 will 的區(qū)別
① 對未來事情的預(yù)測用“ will + 動詞原形”表達，will 沒有人稱和數(shù)的變化，變否定句要在will 后面加not, 也可用will 后面加 not,或者縮略式won’t, 變一般疑問句將will 提至 句首。Will planes be large in the future? Yes, they will. / No, they won’t.
②will 常表示說話人相信或希望要發(fā)生的事情，而be going to 指某事肯定發(fā)生，常表示事情很快就要發(fā)生。I believe Lucy will be a great doctor.
③ 陳述將來的某個事實用will. I will ten years old next year.
④表示現(xiàn)在巨大將來要做的事情用 will.I’m tired I will go to bed.
⑤ 表示意愿用will.I’ll tell you the truth.
⑥ 表示計劃、打算要做的事情用 be going to, 而不用 will.
